r - 如何避免列表命名的 unlist() 修改

Question

我对 unlist() 产生的名字有点困惑.请考虑以下 MWE

vector1 <- c(1,2,3,4,5,6,7,8,9,10)
names(vector1) <- c(1,2,2,3,4,4,5,6,6,6)
names(vector1)
# [1] "1" "2" "2" "3" "4" "4" "5" "6" "6" "6"
list1 <- split(vector1,names(vector1))
names(list1)
# [1] "1" "2" "3" "4" "5" "6"

但是之后

names(unlist(list1))
# [1] "1.1" "2.2" "2.2" "3.3" "4.4" "4.4" "5.5" "6.6" "6.6" "6.6"

根据 unlist() 的文档

By default, unlist tries to retain the naming information present in x.

所以我无法理解这种特殊行为。

我的问题是由 unlist() 创建的名称无法与原始名称匹配 vector1 .

Answer 1

unlist(unname(list1))
#  1  2  2  3  4  4  5  6  6  6 
#  1  2  3  4  5  6  7  8  9 10
